    What is the answer of this differential equation.

    ((d^2) r)/((ds)^2) +(m/(r^2)) -(nr/3)=0

    the boundary conditions (i) r=a when s=0 and (ii) dr/ds =0 when r=b.

    m and n are constants.

    hi kumudumalee! welcome to pf! :smile:

    (try using the X2 button just above the Reply box :wink:)

    multiply the whole equation by dr/ds, and then integrate :smile:
